Monarda plant named ‘Domonpocre’

ABSTRACT

A new and distinct cultivar of  Monarda  plant named ‘Domonpocre’, characterized by its upright plant habit; freely branching habit; dark green-colored leaves; freely flowering habit; large inflorescences with light red purple-colored flowers; and relative tolerance to Powdery Mildew.

Botanical designation: Monarda didyma.

Cultivar denomination: ‘DOMONPOCRE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Monarda plant, botanically known as Monarda didyma, typically grown a container plant and hereinafter referred to by the name ‘Domonpocre’.

The new Monarda plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program is to create new compact and freely branching Monarda plants with numerous attractive flowers.

The new Monarda plant originated from a cross-pollination in 2009 of Monarda didyma ‘Pink Lace’, disclosed in U.S. Plant Pat. No. 18,367, as the female, or seed, parent with Monarda didyma ‘Cambridge Scarlet’, not patented, as the male, or pollen, parent. The new Monarda plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment in Aalsmeer, The Netherlands in 2010.

Asexual reproduction of the new Monarda plant by vegetative terminal cuttings in Aalsmeer, The Netherlands, since 2011 has shown that the unique features of this new Monarda plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Monarda have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Domonpocre’. These characteristics in combination distinguish ‘Domonpocre’ as a new and distinct Monarda plant:

-   -   1. Upright plant habit.     -   2. Freely branching habit.     -   3. Dark green-colored leaves.     -   4. Freely flowering habit.     -   5. Large inflorescences with light red purple-colored flowers.     -   6. Relatively tolerant to Powdery Mildew.

Plants of the new Monarda differ primarily from plants of the female parent, ‘Pink Lace’, in the following characteristics:

-   -   1. Plants of the new Monarda are more freely branching than         plants of ‘Pink Lace’.     -   2. Plants of the new Monarda are more tolerant to Powdery Mildew         than plants of ‘Pink Lace’.

Plants of the new Monarda differ primarily from plants of the male parent, ‘Cambridge Scarlet’, in the following characteristics:

-   -   1. Plants of the new Monarda are more freely branching than         plants of ‘Cambridge Scarlet’.     -   2. Plants of the new Monarda are more tolerant to Powdery Mildew         than plants of ‘Cambridge Scarlet’.

Plants of the new Monarda can be compared to plants of Monarda didyma ‘Sugar Lace’, disclosed in U.S. Plant Pat. No. 22,918. In side-by-side comparisons, plants of the new Monarda differ primarily from plants of ‘Sugar Lace’ in the following characteristics:

-   -   1. Plants of the new Monarda are more compact than plants of         ‘Sugar Lace’.     -   2. Plants of the new Monarda have thicker lateral branches than         plants of ‘Sugar Lace’.     -   3. Plants of the new Monarda have larger leaves than plants of         ‘Sugar Lace’.     -   4. Plants of the new Monarda have slightly darker red         purple-colored flowers than plants of ‘Sugar Lace’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Monarda plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Monarda plant.

The photograph is a side perspective view of a typical flowering plant of ‘Domonpocre’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the summer in 13-cm containers in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Monarda production. During the production of the plants, day temperatures averaged 20° C. and night temperatures averaged 16° C. Plants were pinched one time after planting young plants and were four months old when the photograph was taken and 25 weeks when the description was taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
